REE-LING MACHINE.

Application filed August 21, 1825. Serial No. 51,604.

This invention relates to machines for reeling various fibrous materials and especially adapted for winding or reeling silk, and has for its object to provide a machine of this character in which a new and improved electrically operated means is employed for automatically stopping the winding operation when for any cause a thread breaks or runs out.

Another object is to provide an electrically operated means which is normally inoperative and only thrown into operation by the movement of a detector or faller which is released by the breaking or running out of a thread.

Another object is to provide a registering device which may be set at a predetermined point to electrically operate a signal and stop the winding mechanism.

Another object is to provide certain i1nprovements in the form, construction and arrangement of the several parts whereby the above named and other objects may be effectively attained.

A practical embodiment of our invention is represented in the accompanying drawings, in which Fig. 1 represents a detail vertical section of one end of a reeling machine having the driving mechanism and adjacent parts to which our improvements have been applied,

certain of the parts being broken away to show other parts more clearly.

Fig. 2 represents a similar view of the parts shown in another position.

Fig. 3 represents a detail vertical section taken in the plane of the line.IIIIII of Fig. 2, looking in the direction of the arrows.

Fig. 4 represents a detail elevation, on an enlarged scale, of a portion of the tripping mechanism of the registering and signaling device, and I Fig. 5 represents a detail section taken in the plane of the line VV of Fig. 4.

In the drawings, we have shown only one end of a reeling machine, it being obvious that standards and end frames serve to support the opposite end of the several shafts, rods, bars and shelves in brackets and bearings similar to those hereinafter described.

A portion of one of the vertical standards of the machine is denoted by 1 and the horizontal shelf by 2, which extends from one i standard to the next standard.

The supply spools are mounted on pins 4 carried by the shelf 2. The thread 3 from each spool passes upwardly over a guide rod 5, and downwardly over guide rods 6 and 7, thence-through a loop 8 of a detector o' r faller 9, and through guide eyes 10 carried by a reciprocating traverse bar 11 to a reel 12. The detectors or fallers are each mounted to independently rock on a rod 13 fixed in and between the standards. Each detector is so arranged that while a thread is passing through the loop 8, the detector will be held a ainst a rod -14, but when the thread brea s the detector will be released and fall by gravity to rest on a bar 15 carried by brackets 16 dependin from the shelf 2. This bar 15 is insulate from the bracket and frame by any well known and approved means.

The reel 12 is removably mounted to rotate with a pulley 17 in any well known or approved manner, which pulley is secured to a stud shaft 18 carried by a. swinging arm 18* pivoted on the standard 1.

Power is applied to a drive shaft 19 from a suitable source (not shown), which shaft has mounted to rotate therewith'a pulley 20 arranged in position to frictionally drive the reel pulley 17 on the stud shaft 18, in the usual manner.

Motion is imparted to the traverse bar 11 from the stud shaft 18 through spur gears -21, 22, and bevel gears 23, 24 of which the bevel gear 24 is carried by an inclined shaft 25 mounted in bearings 26, 27 offset from the standard 1. The upper end of the inclined shaft 25 is provided with a crank 28, which has a pin and slot connection with a bracket 29 fast on the traverse bar 11 in the well known manner.

A brake lever 30 has one end pivoted on a pin 31 fast on the standard 1 and is provided with a friction pad 32 which is adapted to be brought into contact with the pulley 17 to lift the same so that it will contact with a friction pad 33 carried by a stud 34 fixed on the standard and arran ed to overhan the pulley 17. The brake Fever 30 is yiel ingly held in position by means of a rod 35 pivoted at 36 and extending downwardly through an ear 37 secured to the standard 1, between which ear and adjustable nuts 38 threaded on the rod 35, a s ring 39 is interposed. A latch 40 pivote at 41, is arranged to engage a In 42 carried by the brake lever 30 and yiel ingly held in contact therewith by means of a spring 43. The brake lever 30 is also provided with a handle 44 by which it is manipulated to place the In 42 and latch 40 in cooperative relation. T e latch 40 is rocked away from the lug 42 by the following means A member 45 is pivoted at 46 and provided with a curved toe 47 which is arranged to coact with a finger 48 carried by the latch 40. This member 45 is also provided with an arm 49 having a weight 50 at its outer end, which is intended, when free to over balance the member 45, rock the toe 47 and therebyactuate the finger 48 and latch 40. The weighted arm 49 is held in position, as shown in Fig. 2, by means of a bell crank 51 pivoted at 52, one end of which is provided with a notch 53 arranged to engage a lug 54 projecting from the weight 50 on the arm 49. A depending arm 55 of the bell crank 51 forms the armature of an electromagnet 56 and is arranged to be actuated thereby. The electromagnet 56 has one pole connected by a wire 57 to the bar 15 while the opposite pole is connected to a spring contact finger 58, which coacts with a similar spring con* tact finger 59. This spring contact finger 59 is connected by a wire 60 to one pole of a battery 61 while the other pole of the battery has a wire 62, which is grounded at 63 on some part of the standard 1 which is in electrical contact with the rod 13 upon which the detectors 9 are pivotally mounted. The spring contact fingers 58, 59 are normally spaced apart and held in closed position by a pin 64 of insulated material, which pin is fixed in a projection 65 offset from the wei hted arm 49.

rom the foregoing, it will be seen that when one or more of the detectors fall upon or come in contact with the bar 15, the electrical circuit will be closed and the battery 61 will energize the electromagnet 56, which in turn will attract the armature 55, lift the notch 53 from the lug 54 on theweight 50 and allow the arm 49 of the member 45 to rock by gravity on its pivot 46 so that the toe 47 will engage the finger 48 and actuate the latch 40. When the latch 40 is released from the lug 42 the spring 39 on the rod 35 will exert its pressure on the brake lever 30, which will be raised so as to bring the friction pad 32 thereon into engagement with the pulley 17 and force it upwardly against the friction pad 33 on the stud 34.

This downward movement of the weighted arm 49 also causes the pin 64 to move away from the contact fingers 58, 59 and permit them to spring apart and break the electrical circuit, thereby deenergizin the electromagnet 56 which immediate y releases the armature 55 and the bell crank 51 falls to the position shown in Fig. 1.

In order to reset the brake lever and actuate the member 45 simultaneously, we provide a rocking element 66 pivoted at 67 and having oppositely disposed arms 68, 69, of which the arm 68 is arranged to be engaged by an abutment 70 having a screw threaded adjustment on a rod 71, the upper end of which rod is pivotall connected at 72 to the brake lever 30, whi e the lower end of the rod may be connected to a foot treadle (not shown). A rod 73 is pivotally connected to the wei hted arm 49 at 74 and is provided with an a utment 75 which is screw threaded on the rod 73 and may be adjusted in position thereon to be engaged by the arm 69 of the rocking element 66.

Thus it will be seen that as the brake lever 30 is pressed downwardly'against the tension of the spring 39 on the rod 35 the abutment 70 on the rod 71 will be brought into en agement with the arm 68, which will roci the element .66 and raise the arm 69 into contact with the abutment 75, which in turn will move the weighted arm 49 upwardly until the lug 54 is brought into engagement with the notch 53 of the bell crank 51. This upward movement of the weighted arm 49 lifts the toe 47 away from the finger 48 of the latch 40 and allows the latch to be moved by its spring 43 so as to engage the lug 42 on the brake lever 30.

For registerin the length of yarn to be reeled, we provide a spur gear 76 mounted on a stud shaft 77, which spur gear 76 meshes with-the spur gear 21 on the shaft 18. A worm 78 is fixed to rotate with the spur gear 76 and arranged to engage the teeth of a worm wheel 79 fast on one end of a shaft 80 carried in bearings 81, 82 mounted on the standard 1. The other end of the shaft 80 has a worm 83 which meshes with a worm wheel 84, the side of which is divided into sections indicating in the present instance, yards. The numerals illustrated on the side of the worm wheel 84, are placed at one fifth of a circumference apart, the interval between two numbers being the distance which the registering wheel will move for winding two hundred yards.

The worm wheel 84 is provided with an elongated hub 85, (see Fig. 3) the outer end of which has a screw threaded enga ement with a stud 86, secured to one arm 8 of a bell crank lever 88, which is pivoted at 89 on the standard 1, so that as the worm wheel 84 is rotated it will be moved laterally on the stud. The worm wheel 84 may be manually moved toward and away from the worm 83 b means of the other arm 90 of the bell cran lever 88, which arm 90 has a pin 91 yieldingly mounted therein and arranged to seat in a recess 92 in a bracket 93 fixed to the standard 1'. When the pin 91 is released from the recess 92 the worm wheel 84 may be swung by the bell crank lever 88 and moved out of mesh with the worm 83. In this osition the worm wheel 84 may be rotated in a reverse direction by hand to the starting pointof measurement. The position for starting the measurement is determined by a stop 94 on the worm wheel 84 comin in contact with a stop finger 95 adjust-ab y mounted on the standard 1. In order to provide for the stoppage of the machine after a predetermined quantity or length of thread has been reeled, we provide 'an index finger 96 having a split collar 97 ad'ustably secured on the hub and a tai 98. The index finger 96 indicates the number of yards to be reeled while the tail 98, which is diametrically opposite the finger is constructed to engage a spring actuated bell crank latch 99 pivoted at 100 on an ear 101 extending outwardly from the hub of the fixed friction ad 33. One arm 102 of this latch 99 has a ug 103 arranged to be engaged by an abutment 104 on the tail 98, while the other arm 105 is provided with a notch 106 which coacts with a hook 107 offset from a finger 108 of an oscillating sig nal 109. This signal 109 is mounted to rock on a pivot 110 carried by the ear 101 and is held in the position shown in Fig. 2 by the coaction of the notch 106 and hook 107. When the signal 109 is tripped by the abutment 104 striking the lug 103, it will rock the latch 99 so that the notch 106 will be free of the hook 107 and the signal 109 will fall by gravity to the position shown in Fig. 1 and in dotted outline in Fig. 4. In this'position the finger 108 will contact with a pin 111 which is insulated from thestandard 1 and is connected by a wire 112 to the wire 57 of the electrical circuit previously described.

It will therefore be seen that since the signal 109 is grounded on the standard 1, the finger 108 contacting with the stop pin 111 will form the connection to complete the circuit and the battery 61 will energize the electromagnet-56 which will attract the armature 55, lift the notch 53 from the lug 54 of the weight 50 and allow the arm 49 to rock on its pivot 46 so that the toe 47 will engage the finger 48 and actuate the latch 40. When the latch 40 is released from the lug 42 on the brake .lever 30 the spring 39 will exert its pressure on the brake lever 30, which will be lifted, causing the pad 32 to engage the pulley 17 and force it against the friction pad 33 on thestud 34, thereby disengaging the pulley 17 from its contact with the drive pulley 20 and stopping the rotation of the reel 12.

In order that the signal may be visible, at the proper moment, we provide a guard or shield 113, shown in dotted outline in Fi 1, 2 and 3, which guard is spaced a slig t distance from the worm wheel 84 so that the signal may move therebetween and be obscured from view, when in the position shown in Figs. 2 and 3. This guard may be supported from the standard 1 in any well own or approved manner and extended around the worm wheel 84 to serve as a protection therefor.

It will also be understood that as the weighted arm 49 is moved downwardly the insulated pin 64 will be moved away from the contact finger 59 so that the fin ers will spring apart and break the electrica circuit thereby de-energizing the electromagnet 56,

which releases the armature 55 and the bell crank 51 falls to the position shown in Fig. 1.

It will be understood that various changes may be resorted to in the form, construction an arrangement of the several parts without departing from the spirit and scope of our invention; and hence, we do not intend to be limited to the details herein shown and described, except as they may be included in the claims.
